Basically, have you ever thought a character/thing from a Game was OP (Overpowered) or UP (Under-powered)? If so, why do you think it is OP/UP?

Just remember to keep your answers Non-Pokémon related.

For my opinion, Super Sonic (From Sonic The Hedgehog Series) and all the other Supers were OP. This is because the character would make the game twice as easy for you (There is a few exceptions such as Wing Fortress Zone from Sonic The Hedgehog 2), and it does become a bore in the end. Invincibility from all enemies (Except oblivion) is really OP in my opinion.
